Title:Comparative analysis of gut microbiota in long-tailed macaques: Habitat and genetic influences on microbial profiles
The environment, diet, and host genetics play a pivotal role in shaping hosts' gut micro biota composition and health. This study investigates the comparative analysis of gut micro biota between four populations of long-tailed macaques (Macaca fascicular is) including two phylogenetic ally distinct subspecies (M. f. fascicularis and M. f. aurea) inhabiting two habitat types (mangrove forest and island). Employing the full-length16S rRNA gene sequencing on a Nan pore platform, the study investigated the bacterial species richness and evenness between the two subspecies at two habitat types. Two M. f. fascicular is populations that were exposed to anthropogenic food sources exhibited higher bacterial diversity in their gut micro biota compared to their M. f. aurea counterparts living in respective habitats. While Firm cutes and Bacteroidetes emerged as the predominant bacterial phyla within the gut micro biota of both subspecies, however, their relative abundances displayed significant differences. M. f. aurea displayed notably higher relative levels of these phyla compared to M. f. fascicular is. Furthermore, the differential species abundance analysis by LEfSe revealed variations in the gut micro biota between M. f. fascicular is and M. f. aurea, indicating dietary differences corresponding to their respective habitats. In conclusion, this study underscores the intricate relationship between environment, diet, host genetics, and gut micro biota in non-human primates. The study contributes to a broader understanding of how host-environment interactions modulate gut micro biota, emphasizing the role of dietary habits in shaping these microbial communities.
